How to Use Redarc Tow-Pro Liberty

Adjusting the braking settings on the Tow-Pro Liberty is super simple. To get more power output - the maximum amount of power that will be applied to your trailer's brakes - rotate the knob clockwise toward 10. To decrease the power output, rotate it counterclockwise toward 0.

When you apply the tow Toyota RAV4's brakes, the knob will change from blue to red to signal that the trailer brakes are being activated. The higher the braking power output, the deeper the red that you will see.


Manual Override

To engage manual override, simply press the control knob. This will activate the trailer's brakes and brake lights independent of your tow Toyota RAV4, great for stopping sway or controlling your trailer's momentum in an emergency.


How to Calibrate Redarc Tow-Pro Liberty

When you are calibrating the brake controller for the first time, the LED lights will signal your progress.


You'll start by braking 20 times or so to let the unit learn its orientation and the direction of travel. You don't need to have a trailer connected for it to calibrate; the only difference is that the knob won't illuminate at all. If your trailer is connected, the LED light will flash green/blue as it calibrates. When the display turns solid blue, initial calibration is complete.

Once done, the unit will remain calibrated. If recalibration is required, it will happen automatically and without LED indication.


How to Install Redarc Tow-Pro Liberty

The Liberty has almost no mounting restrictions. It comes in 2 pieces: the main unit and the control knob. The main unit mounts out of sight and out of the way. You don't have to worry about dinging your knee on a bulky brake controller or interfering with your Toyota RAV4's airbags.


The control knob can be installed in any convenient spot that's easy for you to see and access. This can be a blank switch panel, an open spot on your center console, or wherever there's space on your dashboard. A universal mounting panel is included to ensure a clean, from-the-factory look. Custom-fit panels are available for certain Toyota RAV4s as well. Before you do any drilling, be sure there's enough clearance behind the dash for the entire knob to install!

Once you've decided where you want to put the control knob, you'll need to find a good place to install the main unit. Your only restriction is the 3' cable connecting the main unit and the control knob. Securely mount the box using screws, double-sided tape, or zip-ties (not included). A mounting kit (RE67FR - sold separately) is also available for the Tow-Pro Liberty. Do not attach the module to wiring or cables that can shift as you drive!


A Toyota RAV4-specific wiring harness (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your Toyota RAV4, and the other end will either plug directly into the controller or will splice into the included wiring harness - no need to hardwire to your Toyota RAV4.


If a custom brake control wiring adapter is not available for your Toyota RAV4, you will need a universal wiring harness (RED69FR - sold separately). A 30-amp circuit breaker kit (331-CBK30-EB - sold separately) may also be required for installation.


Note: If you don't already have a 7-way plug at the back of your Toyota RAV4, take a look at our exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately).

What is Proportional Braking?

What is proportional Braking

Proportional braking means that your trailer brakes mimic your tow Toyota RAV4's brakes. If you slam on the brakes in your Toyota RAV4, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your Toyota RAV4's braking. This saves wear and tear on the tires and the brakes on both your Toyota RAV4 and trailer.


The Tow-Pro Liberty uses an internal 3-axis accelerometer to sense how your Toyota RAV4 is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow Toyota RAV4 and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
